1. Claim.

1 This invention relates to an air conditioning apparatus and it is primarily an object ofthe invention to provide an apparatus of this kind which can be employed with equalfacility in either raising or lowering the temperature of the-- wherein there is provided withinthe housing between the compartments, means for conditioning the air stream as by either raising. or lowering the temperature thereof.

Another object of the invention is to provide. an apparatus of this kind wherein a streamof. air is caused to flow therethrough and wherein such stream or air has contact with heatedsur faces, whereby the air, when vitiated,,mayrbe restored.

An additional object of the inventionnis. to: provide an apparatus of this kindcomprising1a. housing through which the air to be treated is. directed and wherein means are providedzfonfiletering the air before entering the housingzand:

also for again filtering the air aftenbeingtreated; 30

and before leaving the housing.

The invention consists in the details of.construction and in the combination and-arrange ment of the several parts of my improved: air con ditioning apparatus whereby certain important advantages are attained, as will be hereinafter more fully set forth.

In order that my invention maybebetter un--- derstood, I will now proceed to describe the same":

with reference to the accompanying drawings; wherein:

Figure 1 is a diagrammatic view andalsopartlw in elevation and partly in section of an"air-*conditioning apparatus constructed inaccordance with an embodiment of the invention;

Figure 2 is a horizontal sectional-viewtaken through the upper portion of Figure 1;with'the filtering elements diagrammatically illustrated withdrawn;

'Figurefi is. axview inside elevation. of the-apparatus r; as herein embodied;

Figure 41s a View in'top plan;.and-

Figure 5 is aview inzend elevation.

;In. the. embodiment of the inventionlasedisclosed in theaccompanying drawings, H denotes aahousingof desired dimensions 'andlwhich is herein disclosed as rectangular inform and-ofa size tobe-readily transported to be placed Jas=required as..within a room. ofabuilding or within therinterior of anautomobile .body. The use of the-.ap.paratusforms .no' particular .part of..th'einvention.

.x'Ihe housing H has. depending fromits. corner, One end portion portions; the supporting legs 1 of the housing H is divided, by apartition 2 exe tending from the bottom Wall 3 of the housing H and. stoppingshort ofthe topthereof leaving'anair port 2 thereover.

"This partition with the adjacent end wall Z'Of the housing provides a. fanchamberc at .onecend of. the housing, the top of whichisclosed by a. door 4 hereindisclosed as of a swinging type 819 thoughsuch door maybe of other desired conbe positioned.

Normally disposed over the bottom wall 3" is an.-

air filtering element 5 herein disclosed as of. a

sliding. or drawer type andwhich can be moved: intoposition across the bottom of the chamber (3. or. withdrawn therefrom through a suitably p o-- sitionedopening 6 in the front side wall I of the;

housing 3.

jThe. upper portion of the partition is pro vided with the openings 8 whereby the air stream; createdby the fan F may pass therethrough and.

which. flow of the air stream maybe controlled in. any conventional manner as by the. use wof shutters, not shown, to which ready access may be hadiwhen the door 4 is in openposition.

As herein embodied, thefanF is mounted upon. therupper end. portion of the vertically-disposed drive shaftl I of anelectric motor I 2;. This motor l2, togetherwith the shaft I l issupported in the 3 central portion of the chamber C from the braclb et l4 extending inwardly of the chamber from the rear side wall i5 of the housing H.

The end of the housing H remote from the chamber C is divided by the partition l6 extending from the top of the housing to a point closely adjacent the bottom wall 3 thereof whereby is provided a discharge compartment D to which access is had through the opening 11 afiorded by the space between the lower end of the partition I6 and the bottom wall 3.

The front side wall I at the upper portion thereof is provided thereacross with the louvers I! through which passes out air from within the compartment D. The top of this compartment D is closed by a door l9 herein disclosed as of a swinging type although it can, if desired, be otherwise. This door l9, when opened, permits the desired placement within the lower portion of the compartment D of a container for water or Dry lee.

This container 20 is provided with an upstanding filler spout 2| to permit the ready placement of water or Dry Ice within the container C with out necessitating removal of the air filtering element 22. This element 22 is also of a slide or drawer type and is readily insertible within the chamber D or removed therefrom through a proper opening 23 in the front side wall I of the housing immediately below the louvers. One corner portion 24 of the air filtering element 22 is cut out in order to allow the spout 2| of the container 20 within the compartment D to extend as desired above the applied filtering element 22.

The top of the housing H between the partitions 2 and I6 is also initially opened but is normally closed by a removable lid or top member 25. Depending from this lid or member 25 at points spaced lengthwise thereof are the baflie plates 26 of metal which are of a length to terminate above the bottom 3. These baflie plates 26 are also positioned centrally between the upstanding bafile plates 21 carried by the bottom wall 3 and terminating below the top of the housing H. One end baflle plate 26 is positioned between the partition 2 and a baiile plate 21 while one of the bafiie plates 21 is positioned between the partition 16 and a bafiie plate 26.

The bafiie plates 26 and 21 coact to provide means whereby the air stream as forced through the housing H by the fan F will travel in a tortuous path and in a manner to have contact with the bailie plates 26 and 21 which, when said bafile plates 26 and 21 are properly heated, will result in altering the physical character of the air in the stream in a desired manner.

Arranged at opposite sides of each of the bailie plates 26 and 21 are batteries of vertically spaced electrical heating units 28 which are supported upon one side wall and provide the requisite means for eifecting the heating of the plates 26 and 21 and the air passing through the housing H. In the present embodiment of the invention, these various heating elements 28 are electrically connected through the conductors a with a multipole switch 29 adapted to have connection with a source of electrical energy in the usual manner.

This multi-pole switch 29 may be of any type and provides means whereby all or any desired number of the units 28 may be caused to operate. The switch 29 in the present embodiment 01' the invention is carried by the front side wall I which also carries a switch 30 for connection with a suitable source of electrical energy and with which switch 30 is also electrically connected the motor I 2 through the conventional conductors b.

When it is desired that the apparatus be employed ior cooling the atmosphere, Dry lce may be placed within the container 20 and, of course, the heating elements 28 will be closed off.

The end wall oi oi the housing l-l associated with the compartment D is provided in its upper part with a relatively large opening 32; normally closed by a removable cap 33 or otherwise as may be preferred. This opening 32 provides an outlet which can be readily used should it be desired to couple to the apparatus a nexible tube to conduct the treated air to other localities or should it be desired to use heated air as a windshield defroster.

It is also to be stated that the major portion of the top oi the container 20 is open so that when water is placed in the container as the heated air passes through the compartment D over the top of the container, effective humidification of such air will be had.

The bottom wall 3 oi the compartment D has depending therefrom a conventional drain cook 34.

From the foregoing description it is thought to be obvious that an air conditioning apparatus constructed in accordance with my invention is particularly well adapted ior use by reason of the convenience and facility with which it may be assembled and operated.
